Inclusive kinematic distributions represent a portal to a precise
determination of the HQE parameters and \(|V_{cb}|\) . Lepton energy moments and
moments of hadronic invariant mass have been extensively measured at \(B\) 
factories and their prediction is know up to next-to-next-to leading order
(NNLO) for free
quarks [1]}, [2]}, [3]}, [4]}, and
next-to-leading order (NLO) at order
\(1/m_b^2\)  [5]}, [6]}, [7]}. Moments of the
leptonic invariant mass have also received attention in the recent years due
to their dependence on a smaller set of HQE parameters [8]}.
Results for the NLO corrections up to \(1/m_b^3\)  have been presented
in [9]}.
